    Preheat the Oven

    Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish.

    Mix Dry Ingredients

    In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until well combined.

    Combine Wet Ingredients

    In another bowl, whisk together the melted butter, eggs, and vanilla extract until smooth.
